Answer:
Step-by-step explanation:
⅓x + 7 = -2
isolate the x term by subtracting 7 from both sides
⅓x = -9
Multiply both sides by 3
x = -27
Answer: Dim Col A = 4.
Step-by-step explanation:
Since we have given that
Matrix A has 5 rows and 8 columns.
And Nul A = 4
It implies that the rank of A would be
Number of columns - Nul A = 8 - 4 =4
So, rank A = 4
so, it has dim Col A = 4 also.
But the four vector basis lie in R⁵.
Hence, Dim Col A = 4.
30 x 10 = 300 i hope this helps
Answer:
4/5
Step-by-step explanation:
constant of proportionality is slope which is rise/run the graph goes up 4 (rise) and right 5 (run)
To do this you have to round the 3. It is the same things as asking to round to the ones place.
To the right of the 3, is a 1. Since this digit is not bigger than a 5, the 3 stays the same.
Your answer is 3
